The primary risk. If the stock drops significantly, the premium you collected won't be enough to offset the loss.
Example
You own AAPL at $230 and collect $420 selling the $240 call. The stock drops to $210 — that's a $2,000 unrealized loss, offset by only $420 in premium. Your net loss is $1,580.

What if I'm still worried about risk?
That's normal — and honestly, a healthy amount of caution is a good sign. It means you're taking this seriously.
The most important thing to remember: the risk of a covered call is the risk you already took when you bought the stock. Selling a call doesn't add risk — it reduces it by lowering your cost basis. If you're comfortable owning the stock, you're comfortable selling covered calls on it. And if a trade moves against you, there are always ways to roll or close early.

What do covered call sellers ask most often?
What is the biggest risk of selling covered calls?+
The biggest risk is the underlying stock declining more than the premium you collected. For example, if you collect $400 in premium but the stock drops $2,000, your net loss is $1,600. This is the same risk as owning stock — covered calls actually reduce it by lowering your cost basis.
Can I lose all my money selling covered calls?+
In theory, yes — if the stock goes to zero, you lose your entire investment minus the premium collected. But this is the same risk as owning the stock without selling calls. The covered call doesn't add risk; it reduces it. You'd only face this scenario if the company went bankrupt, which is why stock selection matters.
Is early assignment bad?+
No. Early assignment means you sell your shares at the strike price and keep the full premium. In most cases, this is a profitable outcome. It typically happens near ex-dividend dates when the call buyer exercises to capture the dividend. ThetaScout flags these dates so you can plan accordingly.
Should I sell covered calls through earnings?+
Generally, no. Earnings announcements can cause 5-15% stock moves in either direction. While the elevated implied volatility makes premiums look attractive, the risk of a large adverse move is what's driving those higher premiums. Wait until after earnings to sell your next call.
